控制臺報的SQL語法錯誤，很奇怪
自己在DEBUG模式下運行，程序執行到MaintainService下的deleteBatch下的dao.deleteBatch(idList)就報錯
下面是報錯的部分信息：
<==????? Total: 3
==>? Preparing: delete form MESSAGE where ID in( ? , ? )
==> Parameters: 2(Integer), 3(Integer)

找到問題所在了，原因是sql語句寫錯了應該是from 寫成了 form
總結3點想分享給一起努力小伙伴：1.學會使用DEBUG，這是個好東西
2.心細
3.遇到一時解決不了的問題，學會像別人求助或者放一下，讓自己休息一下再來看，效率會高很多。
